Most DOC / DOCX files convert well to eBooks. However, some files with complex formatting may not convert as well. Use the previewer to make sure your book converted successfully, especially if it has graphics or tables. Readers can choose to view Kindle books in different font sizes, so page numbers, font sizes and margins don't apply. Use Word's "Page Break" feature to create intentional page breaks for chapter endings and to separate sections as needed.

Use Word's "Insert" function to insert images into your eBook. Don't copy and paste. Upload your entire manuscript in one DOC / DOCX file. Don't include a cover image in this file. You'll be prompted separately to create your cover image with Cover Creator or to upload your own cover image, and we'll automatically incorporate this cover into your Kindle book.See our Simplified Formatting Guide for more details on formatting eBooks in Word.

For more information on how to use Microsoft Word, check out their support page.

Save your HTML file as Web Page, Filtered (HTM / HTML) (PC) or Web Page (HTM) (Mac). This will create one folder containing the HTML manuscript file along with the image files, which you'll need to compress into a ZIP file before uploading to KDP.

If you don't have images in your manuscript, you can upload your HTML file directly without compressing it into a ZIP file first. For more details, see our HTML-specific Help topics:

• Basic HTML Formatting Guidelines
• Supported HTML Tags
• Custom HTML Tags Supported
• Images
• Paragraphs
• Tables

MOBI is a reflowable file format. We don't allow fixed layout MOBI files. Also, MOBI (.prc) files created with the legacy program MobiPocket Creator are no longer supported.

We support unzipped ePub files. Before uploading, we recommend validating the file with Kindle Previewer. You can also validate the file by using this ePUB checker tool. 

We support RTF files.

We support TXT files for manuscripts that do not contain images. Since KDP converts plain text to HTML, image locations referenced in a TXT file will not convert successfully.

We accept PDF files, but they can contain embedded formatting and/or images that don't convert well to eBooks. If you'd like to upload a PDF file for your book, preview it before you publish. If you see any issues or if your book doesn't look the way you want it to, we recommend converting your PDF to a Word document and formatting it according to our Simplified eBook Formatting Guide.

You can also try using the Kindle Textbook Creator. This is a downloadable tool that helps you convert PDFs that contain rich graphics like charts, graphs, and equations. Learn more about Textbook Creator.

Note: At this time, we only support PDF manuscripts in the following languages: English, French, German, Italian, Portuguese, Spanish, Catalan, Galician, and Basque.

We support Kindle Package Format files. However, if you uploaded your book in DOC, DOCX, MOBI, EPUB, HTML, TXT, RTF, or PDF format and want to change your format to fixed layout, you'll need to unpublish the previous version of your book, then add it as a new title using a fixed layout file format like KPF.

Want to change from a fixed to a reflowable file format? You'll have to unpublish the previous version and then add it as a new title using a reflowable file format such as DOC/DOCX, HTML, MOBI, or ePUB.
